WASHINGTON, April 9 (UPI) -- There may be enough non-food feedstocks for biofuels to meet U.S. renewable fuel proposals, the Union of Concerned Scientists said.
UCS said there are ways to meet targets for the Renewable Fuel Standard without straining food supplies. Oil lobby American Petroleum Institute, often critical of the RFS, said EPA's proposed mandate for 14 million gallons of biofuel for 2013 depends on a "non-existent" commercial cellulosic biofuel sector. EPA's proposal, said API, "is unworkable."
